  1. How ADORABLE, Arp!

    That is a really cool adaptation!

    1. Thanks Lisa :o) Its a cool feature, but quite hard to confirm visually and even harder to clearly demonstrate in a photo - this one came out nicely to demonstrate the colours, but of course the critter had no intention of sitting still to allow for an image with acceptable dof/sharpness :-/ Cheers, Arp Posted 6 years ago

    1. Thanks Ferdy, The recent uploads with the American west coast Ligia by Gary "inspired" me to add these old images :o)
      A Rock Louse, Ligia occidentalis. This poor fellow made the mistake of trying to over winter in a tote that contained our artificial Christmas tree and couldn’t find its way out. The tote was in a crawl space the floor of which is granite that extends to the ocean meters away. A short “crawl” for this fellow when it is warmer. I have tried unsuccessfully to take photos of them before but they are too quick for me quickly disappearing into a crack in the rocks. This fellow was quite large, about 3.5cm!
